Description

Pharmaceutical products known as nanomedicines are those that include nanomaterials or nanoparticles as active or carrier ingredients. Nanomedicines have demonstrated significant potential for enhancing medication delivery, effectiveness, safety, and biocompatibility, particularly for the treatment of difficultto- treat diseases like cancer, infections, and neurological disorders. Nanomedicines do, however, also present a number of difficulties and unknowns with regard to their Pharmacokinetics (PK) and Bio-Distribution (BD) in vivo, which are essential for figuring out their therapeutic benefits and possible hazards.

In relation to nanomedicines, the terms "PK" and "BD" relate to the procedures and criteria that characterize how they are absorbed, distributed, metabolized, eliminated, and accumulated throughout the body and in various organs and tissues. The physicochemical characteristics of NPs (such as size, shape, surface charge, composition, and coating), the route and dose of administration, the physiological and pathological states of the host, and the interactions with biological components (such as proteins, cells, and enzymes) are some of the factors that affect the PK and BD of nanomedicines. Because of this, the PK and BD of nanomedicines vary greatly.

Advanced analytical methods and modeling tools are needed to assess the PK and BD of nanomedicines in vivo. The term "analytical techniques" refers to a wide range of procedures for identifying, measuring, visualizing, and characterizing in biological samples including blood, urine, faeces, tissues, or organs. The following analytical methods are frequently employed: spectroscopy, chromatography, Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), Single- Photon Emission Computed Tomography (SPECT), X-Ray Computed Tomography (CT), Optical Imaging (OI), and Mass Spectrometry Imaging (MSI). The concentration, location, morphology, composition, stability, and interactions in vivo can all be determined using these techniques.

For nanomedicines to effectively treat patients, they must pass through a number of biological barriers in the body, including the blood-brain barrier, the blood-retinal barrier, the mucosal barrier, and the tumour microenvironment. Biological elements like proteins, cells, enzymes, and the immune system must also be avoided by nanomedicines in order to prevent interactions that could impact their stability, biodistribution, pharmacokinetics, and pharmacodynamics. Nanomedicines must be biocompatible and secure for usage in humans, which means they can't have negative side effects including toxicity, inflammation, immunogenicity, or hypersensitivity.

Additionally, nanomedicines must be biodegradable or excretable in order to avoid building up or remaining in the body or the environment. According to the production procedure, storage circumstances, and route of administration, physicochemical parameters such as size, shape, surface charge, composition, coating, morphology, stability, and interactions may have an impact on the effectiveness and quality of nanomedicines. As a result, the study and characterization of nanomedicines requires the use of standardized and established procedures and tools. The PK and BD of nanomedicines in vivo are described, predicted, simulated, and optimized using modeling tools, which include diverse mathematical models and computational techniques. Physiologically Based Pharmacokinetic (PBPK) models, Pharmacokinetic/Pharmacodynamics (PK/PD) models, Population Pharmacokinetic (PopPK) models, machine learning models (e.g., artificial neural networks), Molecular Dynamics Simulations (MDS), Agent-Based Models (ABM), and network models are a few of the frequently employed modeling tools. These instruments are capable of revealing information about the processes, kinetics, dynamics, variability, uncertainty, sensitivity, and optimization.
